You said you couldnt decide to go cheap (lock-rite) or expensive ARB. How about a detroit locker in the rear and an aussie or truetrac in front. Maybe later you could do an e-locker or ARB in front? Yes 4.88s are to low for 31's daily driving. I just had them on my truck with 31's for a while til I got 33's. it took off quick, 1st gear was really short and it screamed on the highway. Do you have a lift? just go 33's with 4.88s. Personally, I am waiting to do a SAS on the front before I lock it. Can't justify spending anymore money on IFS
Edit: it seems like this same question is on here like every week
